                                  boolean recurse)

Scan all immediate children of a node, and append all text nodes into a string. Consider the following example:

  <customer>Joe Schmoe</customer>
  

In this case, calling this method on the customer element returns "Joe Schmoe".

Parameters:

node - - the node to scan

recurse - - a flag to indicate whether or not to recurse into sub-elements

Returns:

- the text string

public static List<Node> asList(NodeList children)

Treat the NodeList as a standard list.

Parameters:

children - - the node list

Returns:

- the list of nodes

getChildNodes

public static List<Node> getChildNodes(Node node,
                                       String tagName)

Get all children of a particular tag name as a list.

Parameters:

node - - the parent node

tagName - - the tag name to select

Returns:

- the list of nodes

toElementList

public static List<Element> toElementList(Node node)

Get all child elements of the given node as a list of elements.

Parameters:

node - - the node

Returns:

- the list of child elements

getLocalOrTagName

public static String getLocalOrTagName(Node node)
